source hard drive not recognised after aborting clone operation

I tried to clone my maxtor 80GB drive to a new 80GB seagate sata drive. The process was taking a long time and getting what seemed a lot of read errors so i aborted with the intention of trying agian later. I elected not to make changes, i expect the dest drive to be incomplete but upon restart my source drive is not valid and windows set up says it cannot access the drive. I cannot access it as a slave drive on another windows system either. Any way i can get my windows partitions back?
